I know Kenny - and that's why I requested a photo.

Jon,

 

If there is a JB stamp anywhere, I think it should be JB138 ( Toyo Jitsugyo )

 

Apparently the company had a complex manufacturing and trading deal with another "limited company" (if you like) called  The Oriental Trading Company, which also used the same JB138 code.

I've gone over it a few times with a magnifier and haven't found any such markings.  The markings on the back are:  Swift Fully Coated, Saratoga 8X,40, 367 ft at 1000yds, Model No. 801, No 6 - 50776

 

The front right: Quartar 8X, RLE 37.5

 

Center cap:  Japan TJK

RLE 37.5  is an expression of a rather primitive measure known as  Relative Light Efficiency.

 

The number following RLE is simply the exit pupil squared ( in this case 5x5 = 25 ) plus 50% ( = 37.5 )

 

The "plus 50%" bit is an estimated "plus factor" presumed for a single layer of Anti-Reflective coatings.

 

The only other Swift Saragona I could find on an old ebay sale was described as having a JB26 number ( Futabu Kogaku ) - the JB represents the place of the finished instrument.

 

 ----   with a JE45 ( JE is for body manufacturer only )

 

This appears to conflict with the TJK stamp.

 

The ebay offering was estimated to be dated circa 1967.

Jon,

 

I suspect this is a JB26 Futaba glass. Does it have a tripod mounting point underneath?

No, they don't have a tripod mount.

So playing around with my newly lubricated CGB 40 MA binoculars today and noticed an enigma maybe someone can help answer/explain. I’ve had these for about a month now and today while outside looking into the RH objective there’s appears to be a ghost image of “BOB 308” that was previously written on the inside of the RH objective. It like it was written in grease pencil and then cleaned off but maybe not completely or it interacted with the coating. Never saw it before until today. It can only be seen outdoors, in certain light and at an angle, otherwise it’s completely invisible. See the image below, if you look close you can make it out, BOB over the top of 308, in the center of the lens. What could it possibly mean and why would someone write it on the lens?

 

attachicon.gif34EBBA85-6A7E-46FF-A4E1-4E893C709236.jpeg

 

Here it is traced

 

attachicon.gif4FA25191-1EA3-4011-9C6A-2EB4284BAE29.jpeg

Could it possible be BOP indicating might have been going to do that modification and for some reason didn't?  Only thing I could think of.  I have same binocular, 1945 but lower serial #,  Going to try and lube occulars tomorrow as yeah, stiff from 75 years of sitting in stores.  Same year I was born so had to buy them.

I hadn't scanned any ads for a few weeks.  Decided to do so the other morning.  Found these almost immediately after they were listed (if the date and time on the ad were accurate) and reached out to the seller without hesitation. 

 

The seller later responded, but they took a long time to get back with me.  They said that they had someone local that was interested.  I told them that if I was the first person to contact her that I would pay a few bucks more, and pay shipping, but that if I was not first that I did not want to buy out from under anyone.  She said I was not first.  I told her I would wait until she knew what was happening with the first contact. 

 

I assumed that I would not hear from her again.  However, she later reached out and told me that the other buyer had not continued to communicate with her.  She said that she would ship them to me, if I was still interested.  I WAS...!

 

They're in great shape.  The case is decent, but missing the strap.  The neck strap is braided leather.  Another set I have also has this type of strap.  They might need some internal cleaning, but no rush.  Sadly, no paperwork, which is always cool.  The seller said that they were her great-grandparents.

WooHoo! Great snag! I Just caught myself another one of these off eBay recently, though I surely doubt my price was as good as yours. Give Grimnir your serial number and he can get you pretty close to a manufacturing date. It's going to be in the 1957 to 1959 range though.

Interestingly enough, I think I might have the date narrowed down.  I noticed a suspicious piece of paper in the case.  It turned out to be a warranty card that was folded in half, and barely still in one piece.  It shows a purchase date of "Mar 1958".

That sounds right. Send me the serial number and I'll check with my data tomorrow.

Hello,

 

I recently acquired a non-zephyr B&L 8x30, my second.  The serial number suggests 1941.  Strangely, it has coated elements which B&L did not introduce to civilian models until late 1945.  In its eighty year life, anything could have happened.  It is possible that B&L offered coating in the post WWII years.  Cory Suddartth did a magnificent job in cleaning and collimating the binocular.  

 

I may get a chance to post a photograph, next week.

 

Stay safe,

Arthur Pinewood

Hello,

 

As promised, here are some photos of this binocular.  It is a noticeable improvement over the non-coated version.  I used it for bird watching over the last few days, without my eyeglasses.  In my backyard I saw male and female common yellowthroats, aka Maryland warblers, a gray catbird, a little flock of blue jays, a female yellow bellied sapsucker and a wood thrush.  

 

Stay safe,

Arthur

Binuxit & B&L.jpg Hello,

 

Here is a comparison photo of the B&L, on the left, and a Leitz Binuxit.  They were made a decade apart but they were contemporaries for many years.  The B&L is bigger and heavier, by four ounces, and has a slightly smaller field of view.  The specs listed on Peter Abrahams web site has only one minute of arc difference but I think the Binuxit is a bit wider than that,  Perhaps one or both companies misstated the specs.  As both are coated, the images are very comparable but I might give a slight edge to the B&L. 

 

Stay Safe,

Arthur

I apologize, but just realized I never followed through with the serial number info.  The number is 314980. 

 

The warranty card had remained folded in half for decades, I assume.  It is quite fragile.  I included a photo for anyone interested.  I really like finding paperwork like this in old bino and telescope cases.

Hi all - I picked up a nice JB-133 bino yesterday - a Tasco 101.  Contrary to many, I really like the old zooms with brass gearing and reasonable ranges - pure fun.  This is my second Tasco zoom and better than my first one.  It was in ok shape when I bought it but the gears were jammed so needed some help.  The rubber eyecups are still super soft and I can easily bend them.  Why binos introduced hard eyecups around the 80s, I'll never know.  I'm thinking the date for this should be mid-60s?

Manufacture of 314980 was probably in 1957 which accords with the March 1958 purchase date on the warranty card.

I recently bought a set of Hilkinson Argus 9x63. They are made in Japan and from the mid 1980s. 

 

Does anyone else have a pair or know anything about them.

There used to be lots of the Dialyt binoculars with the roof prisms, coming from Japan under different brand names.

 

The predecessor is the the Optolyth Royal http://www.optolyth....oyal/index.html , and the Dialyt designs from Zeiss/Hensoldt

 

I used to have one of those 9x63 Dialyts from Japan, a very nice glass even if with a small AFOV.

 

You will enjoy yours,

Thanks JG,

 

Did you every compare to a Zeiss/Optolyth version? Would the Japan one be 75% as good? Or even better?

Hello,

 

I would guess that the Hilkinson is not phase coated, if it is from the 1980's.  Phase coating improves contrast and resolution, so it made roof prims binoculars far more practical.

 

If you have a polarizing filter, put it over the eyepiece and look through the tube.  If the image is split in two, it is not phase coated.

 

Stay safe,

Arthur

I have never had the Zeiss or Optolyth Dialyts for comparison.

 

The new 9x63 Optolyth Royal BGA, all glass Ceralin coated, phase coated prisms, Argon, water resistent, bla bla, is too expensive, even if tempting

https://www.astrosho...9x63-bga/p,1066

 

The Optolyth (Sill) company manufacturing plant is half an hour from where we are living, but never been there.

 

Best,

JG

I know this is late: but it's possible that the cap was put on after the owner lost the original one.  Has anyone else ever seen a TJK-made Swift Saratoga?
